a(1) = 3(1)-1 = 3-1 = 2

a(2) = 3(2)-1 = 6-1 = 5

a(3) = 3(3)-1 = 9-1 = 8

Solve the simultaneous equations by substitution 3 x − 7 y = − 10 x = 5 y + 2
mojhsa [17]

Answer:

3x-7y=-10_{(1)} \\x=5y+2_{(2)}\\

Substituting Equation 2 into equation 1

3(5y+2)-7y=-10_{(3)} \\15y+6-7y=-10\\15y-7y+6=-10\\8y+6=-10\\8y=-10-6\\8y=-16\\y=\frac{-16}{8} \\y=-2\\

Substitute the value of y into Equation 2

x=5y+2\\x=5(-2)+2\\x=-10+2\\x=-8\\

Therefore x=-8, y=-2

Step-by-step explanation:

Have a nice day :)
